CTRL+D, when text is selected, adds extra newline

[Filipe Manuel Azinhal Funenga]

I was looking at the shortcuts available in scratch and found, IMO, a "strange" behaviour in the duplicate shortcut (CTRL+D)

Inside the method action_duplicate, when CTRL+D is pressed and some text is selected, the following instruction occurs:

    if (selected != "") buf.insert (ref end, "\n" + selected, -1);

For me (comparing to the behaviour in Geany), this is not good. Imagine you want to duplicate something in the middle of a line. This is what happens

    "I want to duplicate [this] text"

becomes

    "I want to duplicate [this
this] text"

what I'm used happening in Geany is:

    "I want to duplicate [thisthis] text"

If everyone in the scratch project feels like this is a bug, its just a matter of deleting the '\n' in the "buf.insert(...)" instruction of method "action_duplicate" in the "MainWindow.vala" file.
